Benedict Arnold at Portsmouth

Arnold, after going over to the British, was sent to Virginia to make war on the state. He reached Hampton Roads in December, 1780, raided to Richmond and came to Portsmouth, January 19, 1781. Establishing his headquarters in Patrick Robinson's house, and using the old sugar house on Crawford Street as a prison and barracks, Arnold remained here until spring. Then again he went up the James to open the fateful campaign of 1781 that won the war for America.
